Generally for stored goods or for the ease of extracting article, carriage can be installed on slidably object and slide between fixing object.In order to enable slidably object pull out from the fixing object that slides like a cork and push, carriage is installed as slidably state.Slidably in object representational use case be for custody articles and do not have cover drawer.Drawer can to slide with the shell etc. at furniture, refrigerator, baking box, electronic product on fixing object the carriage fixed be connected and use.

As mentioned above, being fixed with the slip fixed object of carriage applicable is various forms, and it comprises all general object can fixing carriage.In addition, slidably object is the object that can extract on slip fixed object and put into.That is, all general object being connected with carriage and also can carrying out sliding is comprised.

In this manual, will be drawer by the object definitions of sliding for convenience of explanation, the fixing object that slides then be defined as furniture.

That is, drawer can comprise all general slidably objects, and furniture comprises all general slidably fixing objects.

Drawer can be installed as the form that can pull open and push closedown in various furniture.When opening the drawer, owing to there is no lid, therefore easily can check the collecting article of the inside, and it is outwards extracted.In addition, when closing drawers, because it is pushed into inside of furniture, therefore can not be outwardly, thus improve ornamental.Therefore, the storage efficiency of drawer is high, but also easily can take out inner collecting article, thus is mainly used on the furniture such as desk, suitcase, dressing table, file cabinet.

As mentioned above, drawer is by pull-out and push action, slides from furniture.In order to enable drawer slide, respectively carriage can be installed in the both sides of drawer.

Carriage can comprise two sections of overlap modes and three sections of overlap modes.The moving-member that the carriage of three sections of overlap modes can comprise the fixed part be fixed on furniture, intermediate member and be fixed on drawer.Intermediate member, its one end and fixed part Structure deformation, the other end and moving-member Structure deformation, thus be connected and fixed parts and moving-member.Yet forms both at the two ends of intermediate member can Structure deformation in the orbit portion of fixing rail and mobile rail.In the position that fixed part is corresponding with orbit portion with the inside of moving-member, also form rail orbit portion.Also spin is formed with between orbit portion and rail orbit portion.When user pulls out drawer, spin can guide rolling movement, thus rolling limit, drawer limit is pulled out gently.After pull-out, when user pushes drawer, spin will guide rolling movement, and rolling limit, drawer limit is inwardly rolled into gently.

As mentioned above, according to the weight of the drawer being drawn out and pushing and the weight of inner reserve, the heavy burden of effect downwards will be produced.This heavy burden is communicated on furniture by the carriage being installed on drawer two sides.Therefore, carriage should be installed with the structure can bearing above-mentioned heavy burden.

Fig. 1 illustrates U.S. Register patent the 6th, the sectional view of 132, No. 020 upper existing carriage announced.As illustrated in fig. 1, existing carriage 10 can comprise: moving-member 13, fixed part 17, intermediate member 14 between moving-member 13 and fixed part 17.

This existing carriage 10, its fixed part 17 is fixed on table sheet material 16 by extension 12; Its moving-member 13 is fixed on the bottom surface of drawer sheet material 11; The both ends of intermediate portion part 14 form three orbit portions respectively.

Here, moving-member 13 and intermediate member 14, formed between intermediate member 14 and fixed part 17 and be equipped with multiple spin 15, and carry out rolling movement along orbit portion, thus make intermediate member 14 carry out sliding along fixed part 17, moving-member 13 along intermediate member 14, and slide and 10 carry out work by three sections of overlap modes on the whole.

The carriage 10 of this U.S. Register patent the 6th, 132, No. 020 prior art, is equipped with the three row orbit portions that can bear above-mentioned heavy burden respectively with the symmetrical direction that is parallel to each other thereon.Moving-member 13, the center position side of its drawer sheet material 11 and bottom are open state.Moving-member 13, forms orbit portion respectively at the top and the bottom faceted portions of the top of the center position of drawer sheet material 11 and table sheet material 16.Fixed part 17, side and the top in its table sheet material 16 direction are open state.Fixed plate 17, forms orbit portion respectively at the top and the bottom faceted portions of the bottom in table sheet material 16 direction and the center position of drawer sheet material 11.Intermediate member 14, the position corresponding to the spin of the track and Structure deformation that are formed at moving-member and fixed part forms orbit portion respectively.

The tourelle 10 of prior art, the spin 15 on the spin 15 of being installed up and down by table sheet material 16 direction to moving-member 13 on the cross section of carriage 10 and the top that is installed on drawer sheet material 11 center position forms triangle substantially, and jointly props up with intermediate member 14 heavy burden that the weight of drawer sheet material 11 and drawer reserve weight produces.In addition, fixed part 17, substantially forms triangle by being installed on the spin 15 of the upper and lower spin of drawer sheet material 11 center position 15 with the bottom being installed on table sheet material 16 direction, and jointly supports with intermediate member 14.Therefore, on the top of intermediate member 14 with table sheet material 16 direction for corner forms the spin 15 of triangle form.In addition, the bottom of intermediate member 14, with drawer sheet material 11 center position for corner, forms the spin 15 of triangle form on top and the mutual aspectant position of each spin 15.That is, existing carriage 10, places mutual aspectant spin 15 from the lower portion direction, two ends of drawer sheet material 11, thus forms the structure can bearing the heavy burden produced from lower portion direction, drawer sheet material 11 two ends.

But existing carriage, it is equipped with six row tracks up and down, and moving-member, fixed part and intermediate member have the structure contacting with rolling ball rolls and carry out rolling.Therefore, carriage, owing to needing to maintain the structure contacted with the rolling ball rolls being installed on this track by six row tracks, is therefore difficult to the volume reducing this device.

In addition, the carriage of prior art, also needs to make the intermediate member possessing the orbit portion can installing six row tracks, and the shape therefore about repeatedly carrying out sheet material bending the intermediate member manufactured is very complicated.The intermediate member of this complicated shape has also just become the principal element increasing manufacturing cost.

And after pull-out drawer, the heavy burden that the weight of drawer and the weight of drawer reserve produce will concentrate on the bottom of drawer lead direction.Like this, concentrate on the heavy burden of drawer lead direction, act as to reverse to the carriage being fixed on drawer two sides and bear a heavy burden.That is, when heavy burden concentrates on drawer lead direction, the carriage being positioned at two sides will produce to reverse to drawer center position and bear a heavy burden.But, the carriage of prior art, owing to being equipped with the six row tracks of heavy burden that can bear and produce to drawer sheet material direction on the fixed part carrying east part and fixed station table material that drawer is housed face-to-face, therefore can bearing the resistance that the torsion to the effect of drawer center position bears a heavy burden and but greatly reduce.That is, six row tracks and the spin being installed on its track become the structure that can be used to bear the heavy burden that lower portion direction, drawer both sides is formed, and therefore bear a heavy burden unable to torsion.That is, in order to bear the heavy burden of lower portion direction, drawer two ends effect and the six row tracks installed and be installed on the spin of this track, the resistance that the torsion acting on drawer center position is born a heavy burden is reduced greatly.

Like this, when existing carriage continuing produce torsion heavy burden, moving-member and fixed part will deform, and the guerrilla warfare of rocking of drawer increases, and finally becomes the key of shortening its life-span.

In addition, when after pull-out drawer, carriage can produce downward heavy burden in downward direction in lead direction one end, produces upwards bear a heavy burden in its reverse one end.Bear a heavy burden up and down, when number of tracks be two take advantage of multiple can be dispersed.That is, install between carriage each parts that should contact in intermediate member scroll-up/down can 2 take advantage of the dispersed track born a heavy burden up and down of times quantity.That is, the track taking advantage of times quantity of 2, by a spin of Structure deformation and disperse another spin of bearing a heavy burden corresponding to this spin forming combination form, thus disperses the heavy burden that produces equably.But the moving-member of the carriage of prior art is equipped with three row tracks and is installed on the spin on this track, and fixed part because of be equipped with three row tracks and be installed on this track spin and cannot be upwards dispersed and produced in downward direction heavy burden, therefore occur bear a heavy burden concentrate phenomenon.The phenomenon that this heavy burden is concentrated just has become the guerrilla warfare increasing specific direction, has caused the principal element of torsional deflection.

Therefore, need to develop and a kind ofly possess the carriage that the rotary body quantity that can reduce rolling movement to greatest extent stably can support again the structure of heavy burden.

Especially, in the urgent need to developing, under the state that can support heavy burden being installed on drawer two sides, the resistance that the torsion produced by improving subtend drawer center is born a heavy burden increases the carriage in life-span.
